Underinflated tyres can mean your engine works harder and burns more fuel.

In fact – over half of UK tyres are under inflated which is costing motorists up to 1 billion pounds a year in excess fuel ⁽¹⁾. So, we’re on a mission to help people save by keeping their car tyres pumped up with regular pressure checks. Have you checked yours lately?

Tyres deflate naturally at the rate of 2 PSI per month ⁽²⁾ – so it’s important to check your pressure monthly. Be sure to check and pump before long trips too, that way you’ll have a more fuel efficient and safer journey.

How to use a digital tyre inflator

Naomi Schiff shows how you can check and correct your tyre pressure using a digital tyre inflator to keep you safe on the road and help you save fuel.

Did you come to one of our pop-up events?

Together with Kwik Fit, we toured the country during October to help UK motorists check and adjust their tyre pressure. During the two-week activation there were free tyre checks offered at 25 Esso sites, with 1,263 car checks done and 3,842 tyres inflations completed!

*Calculations for fuel saving

Fuel saving may vary depending on factors such as the level of PSI underinflation, type of fuel used, cost of fuel, and/or annual mileage. For details on how the calculations were done, please see this table.
